LondonRoad: London Road network tomography data

In MartinLHazelton/DynamicLatticeBasis: Dynamic Lattice Bases for Z-Polytope Sampling

London Road network tomography data

Description

Data on traffic counts observed at a sequence of points on London Road in Leicester, UK. The aim is to sample the corresponding origin-destination traffic volumes that are consistent with those counts. The dataset appears as a list prepared for that purpose. Components of the list are A (the configuration matrix, which in this case is the link-path incidence matrix); y (observed traffic counts); lambda (assumed mean origin-destination traffic volumes); and MarkovBasis (a matrix with columns corresponding to the vectors in full Markov basis for the resampling problem).

Usage

data(LondonRoad)

Format

An object of class list of length 4.

Examples

data(LondonRoad)
Xsampler(A=LondonRoad$A,y=LondonRoad$y,lambda=LondonRoad$lambda,Model="Poisson",Method="Gibbs",tune.par=0.5,combine=FALSE)
